Homework refers to doing the right kind of preparation before showing up to trade. That includes market and mental preparation.
Over the years I have found that the toughest part of trading is the mental aspect. As a matter of fact, I believe that trading is 95% mental and only 5% skill or knowledge of the markets. I only use one indicator and I believe it’s the most highly sophisticated indicator on the planet….your brain. I have tried almost all the various indicators that are available and I have come to the conclusion that the only thing that works for me is reading the price action the best way I know how.
